Getting around firewall/port block.

I have come across a slight dilemma, I have a wireless connection however the ports I need are blocked off. Is there any easy way to get around it? I can't re-route them at all, I've thought about SSH tunneling but that seems a little messy/slow for what I need to do. I'm trying to play an online video game, and there is no possibility of opening these ports (as I do not have the password, and won't be getting it)..

Any ways of being able to get around this or do I need to find another network? If such is the case are there any good sources of internet I can come across that are relatively cheap? Maybe something like a satellite card of some sort?
